Randomized Controlled TrialCPAP at 10 cm H2O during cardiopulmonary bypass does not improve postoperative gas exchange.
To compare postoperative (PO) pulmonary gas exchange indexes in patients submitted to myocardial revascularization (MR) with or without the application of continuous positive airway pressure (CPAP) during cardiopulmonary bypass (CPB). ⋯ CPAP at 10 cm H2O administered during CPB, although had lightly improved PaO2/FiO2 at 30 minutes post-CPB, had no significant sustained effect on postoperative pulmonary gas exchange. We concluded that in patients submitted to MR, application of 10 cmH2O CPAP does not improve postoperative pulmonary gas exchange.

ReviewPostoperative cognitive dysfunction after cardiac surgery.
Postoperative cognitive dysfunction is frequent in cardiac surgeries leading to major consequences. The physiopathological processes involved in this condition are still not completely elucidated, despite the multifactor character. ⋯ However, according to a vast literature on the subject, these factors are not capable to clarify the totality of the cases, taking us to a genetic base for this neurological sequel. In this revision, we briefly assess the factors involved in this cognitive dysfunction as well as discuss the pharmacotherapy in the prevention of this event.

Case ReportsParasternal approach for redo in ascending aorta pseudoaneurysm.
Aortic ascending pseudoaneurysm is a rare complication following aortic root surgery. The surgical solution of the complication is rather demanding and complex, especially when reaching the mediastinum. ⋯ By using this approach, we minimized bleeding risks and the possibility of aortic rupture. This technique could have the potential to be generally applicable in this complication after further evaluation.
